When `Enumerable#all?` is called without an argument, it should check
whether values are truthy but it doesn't appear to work as expected
for the `newer_than_upstream` hash. In this case,
`{ general: false }.all?` returns `true` when it seemingly should
return `false`. This is preventing autobump from opening PRs for new
versions, so I've updated related `all?` calls to use a block with an
explicit comparison to `true` as a workaround to fix autobump in the
immediate term.
